Hi - I'm new here - so please be gentle.

I recently acquired some Corning Ware PyroCeram - that I always considered amazing material.

The piece in question is a 2.5 qt casserole:

It is Corning Ware and PyroCeramic

This means it is ideal for microwave usage.

Except for possibly the lid:

which has a metal screw holding the handle in place:

Details -

I don't know enough about microwaves to whether it is safe to use as-is - or whether that metal screw is going to cause problems.

If it is - I am asking anyone please for ideas of how to fix the handle in place with some microwave and oven safe material.

A friend has suggested using string and a piece of wood to replace the handle components - this is a good temporary solution - but I thought I'd ask the more experienced here for suggestions.

Of course if that metal screw is actually safe in the microwave since it is under cover - then perhaps my question is moot - but at this point in time I am uncomfortable about that.

Thanks for any suggestions,

Vincent
